Replace the Gear Position Sensor on the transmission. Cost is approximately $350. There is a sensor on the brake that will prevent the gearshift from moving out of park until the brake is pressed down. Before you replace some $350 item in the transmission, make sure it isn't this sensor that is causing the issue.
What to do when the gear is stuck in park on a Honda 2001
A Honda Odyssey 2006 may have a gear shift that gets stuck in park due to a faulty brake light switch, which prevents the shift interlock mechanism from releasing. Additionally, issues with the transmission or a malfunctioning shift cable could also cause this problem. Inspecting the brake lights, shift cable, and related components can help identify the root cause. If the issue persists, consulting a mechanic for a thorough diagnosis is advisable.
Likely your transmission is dying. Google "odyssey transmission" and you will find lots of reports about problems with 2000- 2004 Odyssey transmissions. If you are persistent enough, Honda might help some with the repair.

To shift a Honda Odyssey into D3, first ensure the vehicle is in motion and your foot is on the brake pedal. Locate the gear shift lever, typically found on the center console. Move the lever from the "D" (Drive) position to the "D3" position. This setting allows for optimal engine performance in certain driving conditions, like when towing or driving in hilly terrain.
